You may be able to get this to work using libUrlSetCustomHttpHeaders. This command lets you set the request line and any necessary headers in the http request.

For delete it might work something like this:

  put "DELETE /path/to/resource HTTP/1.1" & cr into tRequest
  put "Host: www.yourdomain.com" & cr after tRequest
  // add any other headers here but above is probably minimum

  get url "http://www.yourdomain.com/path/to/resource"

For PUT:

  put "PUT /path/to/resource HTTP/1.1" & cr into tRequest
  put "Host: www.yourdomain.com" & cr after tRequest
  put "Content-length: <length of data>" & cr after tRequest
 // add any other headers here

post myData to url  "http://www.yourdomain.com/path/to/resource"

You should use "get" for DELETE and "post" for PUT to ensure the libUrl internals behave appropriately. I'm assuming that DELETE requires some kind of response message from the server (haven't looked at the spec for a while). If that's not the case, you may get an error, even if it worked correctly.

After using libUrlSetCustomHttpHeaders, the headers get reset (different from httpHeaders), so you should set this before each call.

I haven't tested either of these before. But worth testing perhaps before building your own from scratch.

Good luck!
